Projectile Motion Equations Derivation

In this lecture ,we study that Projectile motion can be represented by a Quadratic Equation; the quadratic equation in turn will have a parabolic graph. We derive Time of flight / Horizontal Range / Maximum Height and the general equation of motion of projectile. We also understand why sin2θ=2sinθcosθ. 

Best way to understand Projectile motion is by playing Angry Birds!
